Besides the nonlinear regime, XL16 also
studied the kinematic dynamo at a large and small magnetic Prandtl number,
and at different ionization fractions.
They found new regimes of kinematic dynamo, including
the transitional stage in a high-Prandtl number medium with the shift of the correlation length of magnetic fields from
the resistive scale to the viscous scale,
and the damping stage of dynamo in a weakly ionized medium
(see also [1]}).
XL16 predictions on the dynamo behavior resulting from the
weak coupling between neutrals and ions at a low ionization fraction
have been numerical confirmed by the two-fluid dynamo simulation
[2]}.
